[PSA] steem.ws + golos.ws = downtime

in steem-dev •  11 months ago

Just providing a heads up with what's going on surrounding these public API servers.

I've been working on the both of these on and off for the last 3 days since they've both encountered issues of falling behind on blocks, forking off, and now while rebuilding hitting "unlinkable block" errors. With HF19 due tomorrow, and myself still needing to upgrade a number of other servers, I'm taking these both offline.

This morning I woke up after the 3rd replay of node.steem.ws to find

The plan is to decommission the existing public API's I run, both golos.ws and steem.ws, and setup brand new (and upgraded servers).

Apologies for the downtime thus far, and moving into the future. In the mean time, I'd recommend you point your scripts to one of the other public API's available:

  • wss://steemd.steemit.com
  • wss://seed.bitcoiner.me
  • wss://gtg.steem.house:8090

or use @almost-digital's new fancy tool to help find one:

I am not a programmer so I cannot understand the code very well. But it is nice of you to mention that you took your servers down so that people can adjust accordingly. Have fun out there and good luck with future posts!

Looks different ,
Thank you so much for this great article! I start reading this knowing that my ignorance in this field could penalize me but it was so great to learn something New

No need to decline payment on stuff like this, IMO. You're doing fantastic work for the network and the community, Jesta, and you deserve to be richly rewarded for your efforts. We all greatly appreciate your efforts. Thank you!


Hah, for some reason it didn't feel right to say "Hey, my servers are down, I should be rewarded!".

How long does it take to update servers to hardfork 19?


Depends on what kind of server it is, for a witness node it's a couple hours, and for a full API node it can be anywhere from 1-3 days (depending on the configuration and hardware). Replaying the blockchain to a new server is quite the process.


Thanks for putting in all that hard work!

Is this why Poloniex isn't sweeping their wallet ?


No, they are probably running their own server. I'd hope they wouldn't use my node without telling me :)



Thanks @jesta :-)

Though I do not understand this programming and stuff but I appreciate your hard work.

thanks for all the great work you do.
